2027 Mercedes-Benz GLS 580 or AMG® GLS 63: which fits Manchester, NH drivers?
The GLS 580 fits Manchester drivers who want the lower-priced V8 GLS, and the AMG® GLS 63 fits drivers who want the most power in the GLS line. The AMG® GLS 63 makes more horsepower and torque than the GLS 580 and carries a higher MSRP.
Keep reading below, then schedule a test drive in Manchester. Bringing your own numbers to the lot settles this faster than any spec sheet.
Pick the GLS 580 for a lower price, the AMG® GLS 63 for more power
The GLS 580 starts at $120,950 for the 2027 model year, and the AMG® GLS 63 starts at $155,250, both before options (Mercedes-Benz, 2027). At Mercedes-Benz of Manchester, the GLS 580 is the trim to start with if the goal is a V8 three-row SUV without the AMG® price.
The AMG® GLS 63 is the choice for a driver who wants the most output in the line. Its 603 horsepower and 627 lb-ft of torque are the highest figures among the GLS trims the maker publishes. A buyer who wants that performance pays for it in the sticker price.
How much more power does the AMG® GLS 63 make than the GLS 580?
The AMG® GLS 63 makes 603 horsepower and 627 lb-ft of torque. The GLS 580 makes 530 horsepower and 553 lb-ft of torque, according to Mercedes-Benz’s published 2027 specifications.
The gap is real, but it sits in output rather than in towing. Both trims carry the same 7,700-pound maximum tow rating, so a driver who tows a boat or trailer on the way to the Lakes Region gets the same rating either way.
What does a 2027 GLS 580 or AMG® GLS 63 cost a New Hampshire buyer?
The starting MSRP is $120,950 for the GLS 580 and $155,250 for the AMG® GLS 63, both per Mercedes-Benz’s published 2027 pricing. Because New Hampshire levies no general sales tax on goods, nothing is added at purchase for sales tax on a vehicle bought here (New Hampshire Department of Revenue Administration, 2026).
Registration is the cost that does apply. New Hampshire charges a municipal registration permit fee set by the vehicle’s list price and model-year age under RSA 261:153 (New Hampshire General Court, RSA 261:153). The state registration fee for passenger vehicles weighing 0 to 3,000 lbs is $42, or $3.50 per month (New Hampshire Revised Statutes, RSA 261:141, 2026). A buyer should check the town clerk’s figure for the municipal permit before signing.
What are the EPA fuel economy ratings for the GLS 580 and AMG® GLS 63?
The EPA rates the 2026 GLS580 4matic at 14 city, 20 highway and 16 combined. The AMG® GLS 63 4matic Plus is rated 15 city, 20 highway and 17 combined (U.S. Environmental Protection Agency, 2026). Both are hybrid, all-wheel-drive models on a 9-speed automatic.
The one-mile gap between the two combined ratings is small, and the highway figures are the same. A driver who spends most of the week on the highway, on I-93 for example, sees little difference in fuel use. The annual fuel cost on the EPA record is $4,850 for the GLS 580 and $4,550 for the AMG® GLS 63.
How do seating, cargo and towing compare on the GLS 580 and AMG® GLS 63?
Both trims seat seven, with six seats available as an option. Both have 40.3 inches of first-row legroom, 41.9 inches in the second row and 34.6 inches in the third. Both carry 84.7 cubic feet of maximum cargo, and both tow up to 7,700 pounds, all per Mercedes-Benz’s published 2026 specifications.
For a family, the seating and cargo numbers are the same. The choice between these two trims comes down to what the engine does rather than what fits in the back.
What do you get with the GLS 580 and with the AMG® GLS 63?
The table sets the two trims side by side on the maker’s 2027 prices and output and its 2026 towing and EPA ratings.
| Trim | 2027 starting MSRP | 2027 horsepower (hp) | 2027 torque (lb-ft) | 2026 max towing (lbs) | 2026 EPA combined (mpg) |
|---|---|---|---|---|---|
| GLS 580 | $120,950 | 530 | 553 | 7,700 | 16 |
| AMG® GLS 63 | $155,250 | 603 | 627 | 7,700 | 17 |
At Mercedes-Benz of Manchester, the warranty on the whole GLS line is 4 years or 50,000 miles (Mercedes-Benz USA, 2026). Buyers who want a used or certified pre-owned GLS can also browse that inventory on the same lot.
When is the GLS 580 or the AMG® GLS 63 the wrong pick?
The GLS 580 is the wrong pick for a driver who wants the most power in the line. The AMG® GLS 63 is the wrong pick for a driver who wants the lowest price on a V8 GLS. Both trims suit a family that needs seven seats and a 7,700-pound tow rating, so the choice comes down to budget and how hard the car will be driven.
Where the lower price matters most, the GLS 580 is the model to test drive first. A driver who wants more output and is ready to pay for it should drive the AMG® GLS 63 before deciding.
